The answer is the first one: deletion.

Explanation for each option:

  • Deletion: This is the correct answer. A deletion mutation occurs when a base is removed from the DNA sequence. This can lead to a frameshift if the number of bases removed is not a multiple of three, potentially altering the entire downstream amino acid sequence.

  • Substitution: This is incorrect. A substitution mutation occurs when one base is replaced by another in the DNA sequence. This does not involve the removal of a base.

  • Insertion: This is incorrect. An insertion mutation occurs when one or more bases are added to the DNA sequence, not removed.

  • None of these: This is incorrect because deletion is indeed a type of mutation where a base is removed.

In summary, the type of DNA mutation that occurs when a base is removed is called a deletion.
